ROLLING MILL-' Applicationfiled April 27, 1922 SeriaLNo. 557,017."

To alt ac/m it may concern:

Be it known that 1, JOHN W. Snaresnson, a citizen of the United States,residing--at Worcester, in the county of l Vorcester and Commonwealth ofMassachusetts, have invented a new and useful Improvement in a RollingMill, of which the following, toether with the accompanying drawing, is

b n a specification.

' The present invention relates generally to rolling mills. Theinvention resides in a novel combination and arrangement of roll itselfnot only to the rolling and handling trains and auxiliary equipment,which adapts of a diversified product of ordinary steel billets, sheetbar and the like, but also to the convenient production, when desired,of various shapes made'of special alloy steels.

The various features and advantages of the invention are fully set forthin the following description, reference being had to the accompanyingdrawing, the single figure of which is a diagrammatic plan view. of

rolling mill apparatus combined and arranged in accordance with theinvention.

Referring to sald drawing, 1 represents a blooming mill of ordinaryconstruction for the reduction of ingots taken from soaking pits, notshown. By any suitable conveying means,indicated diagrammatically at 2,the product of the blooming mill 1 is car ried to a billet and slab mill3,,the rolls of 'which, preferabl provide a plurality ofdifferently-shaped rows of passes, toogive such variety as may bedesired in the crosssection of the reduced material emerging therefrom,I

The reduced product of roll train 3, con-. sisting of billets, slabs andthe like, is re ceived upon a conveying mechanism 4: of any suitableconstruction and'is carried longitudinally forward in the direction of asheet bar mill 5, constituted by a roll train which provides one or morestands of edging rolls 6, 6. As herein shown, the conveying mechanism 4does not deliver the prodnot of roll train 3 directly to the roll train5, but on the contrary, said roll train 5 receives said product from asuitable longitudinal conveying mechanism 7, which is offset from theline of delivery of conveyingmechanism 4. Interposed between theconveying mechanisms 4; and 7 ,is a suitable of the material.

as rapidly or as slowly as desired, acrossthe interyemng space the,transfer mechanism 8 thus constitutes, in effect, a delay table, thefunction of which is to permit as much or as little time to elapse, asmay be desired,

for the'cooling of such of the (products of the roll train 3 as may needa lower temperatuie for their further" reduction by rolling.

For the disposition of the otherproducts of the mills 1 and 3, provisionis made for the broadside transfervof the same to a suitablelongitudinal conveying mechanism 9, which delivers in one direction to aroll desired. Interposed between the conveying I mechanisms 4 and 9 is asuitable broadside transfer mechanism 13,similar in its capabilities tothe transfer mechanism 8 and operating, when desired, as a delay tableon which to accomplish any requisite cooling livered to the mill 10 bythe conveying mechanism 9, after undergoing reduction in the successivepasses of the roll train, is disposed of in the usual fashion by a shear14v and cooling beds 15; such mechanism, as well as the correspondingshear,l6 and cooling beds 17 which are provided in connection with thesheet bar mill 5, form no part of the present invention and hence neednot be described in detail.

The above described arrangement of apparatus lends itself particularlyto the convenient and expeditious treatment of any of the desiredalloysteel products of the mills 1 and 3, that require the removalofsurface imperfections before any further rolling is done. Such material,as delivered by the transfer mechanism 13 to the conveying mechanism 9,is carried rearwardly by said conveying mechanism and acted uponby ashear 18, the pieces being then disposed for cooling either on thecooling beds 11 oron the cars" 12. Ineither case, such material iseventually delivered in convenient location for the operationofchipping, to remove the surface imperfections, or for any otheroperation required, before further rolling action thereon. In order toheat such material, to prepare it for further rolling, furnaces19 areprovided, and so arranged, with relation to the con= Such material as isdea 'veying mechanism 9, that the billets discharged from said furnacesare received 1 directly on said conveying mechanism, in

, with the conveying mechanism 2, in advance of the reducing roll train3. It is thus possible to procure, when desired, the passage of piecesof large section directly from the blooming mill 1 to the coolingdevices 11 or I claim: 1. Apparatus of the class described, comprising,in combination, longitudinal conveying mechanism for the product of abillet and slab mill, two independent reducing roll trains adapted,selectively, to receive said product-,and a delay table interposedbetween said conveyingmechanism andboth of said roll trains. 2.Apparatus of the class described, comprising. in combination,longitudinal con veying means. for the product of a billet andslabinill, two independent reducing roll trains adapted, selectively, toreceive said product, the center lines of each of said roll trains beingoffset from said conveying 'nieans, and-a broadsidetl2LI1Sf61,CODStltIlting a delay table for cooling the product,interposed between said conveying meansand each of said roll trains.

3. Apparatus of the class described, comprising. in combination, areducing. roll train, conveying means normally operable to delivermaterial directly thereto, and

means for obtaining the cooling, storing, cliipping,,and reheating ofsaid material, prior to its delivery to said roll train.

4. In apparatus of the class described,

.means served in common by said conveying comprising, in combination, abroadside transfer mechanism for the product of a billet and slab mill,a longitudinal conveying mechanism adapted to receive said product;

from said transfer mechan sm, and means,

selectively operable, either to procure the further reduction of saidproduct as received on said conveying mechanism, or to procureintermediate surface treatment and reheating of the. same beforeresumption of rolling.

' 5. In apparatus of the class described, a

reducing roll train, a longitudinal conveying mechanism associatedtherewith and adapted to deliver thereto, means for delivering. materialbroadside to said longitudinal convey ing mechanism, and means forprocurin when *desired, the intermediate treatment of saiddeliveredmaterial, prior to its passagev to said reducing roll tram.

6. In apparatus ofthe class described, a reducing roll train, alongitudinal conveying mechanism adapted to deliver material thereto. aheating device adapted to deliver materlal to said longitudmal conveyingmechanism, and means for delivering material broadside tosaidlongitudinal convey-.

ing mechanism intermediate said roll train and said heating device,whereby to permitreheating of said material prior to its reduction-bysaid roll train. Dated April 17, 1922.
